Mahadakash is nature, the ocean of existence, the physical space with all that can be contacted through the senses. Chidakash is the expanse of awareness, the mental space of time, perception and cognition. Paramakash is the timeless and spaceless reality, mindless, undifferentiated, the infinite potentiality, the source and origin, the substance and the essence, both matter and consciousness, yet beyond both. It cannot be perceived, but can be experienced as ever witnessing the witness, perceiving the perceiver, the origin and the end of all manifestation, the root of time and space, the prime cause in every chain of causation.
